Spi Z3852 Cmm Thread Stylus Adapter M2 Female M4 Male

Product Description

The SPI Z3852 is a CMM thread stylus adapter designed to connect coordinate measuring machine styli and extensions with mismatched thread sizes. It features an M2 female thread on one end and an M4 male thread on the other, allowing techs to bridge incompatible stylus components without additional hardware. Machined from steel for rigidity and dimensional stability, this adapter maintains thread integrity under the light but precise clamping forces used in CMM setups. The overall length is 5mm, keeping added stack height minimal. Metrology technicians and quality lab personnel are the primary installers.

This adapter is used in dimensional inspection and metrology applications where CMM stylus assemblies require thread conversion between M2 and M4 connections. It is suited for bench-top and bridge-style CMMs in manufacturing, quality control, and inspection lab environments. The compact 5mm overall length makes it appropriate for tight probe configurations where minimizing deflection and stack-up error is a priority.

Key Features

• M2 female to M4 male thread configuration for CMM stylus extension compatibility
• Steel construction provides rigidity and resistance to deformation under clamping loads
• 5mm overall length minimizes added stack height in stylus assemblies
• Single-piece adapter eliminates need for intermediate extension components
• Compatible with standard CMM thread systems used across major metrology platforms

Compatibility

Designed as an OEM-style thread adapter for CMM stylus systems utilizing M2 and M4 thread connections.

Installation Notes

Installation is performed by metrology technicians or quality engineers working with coordinate measuring machines. Power down or home the CMM before making any changes to the stylus assembly to prevent probe damage. Hand-tighten thread connections using the torque recommendations specified by the CMM manufacturer for stylus adapters. Avoid using pliers or pipe wrenches directly on the adapter body, as this can distort threads and compromise measurement accuracy.
